<blockquote>now I'm out measuring the floor.<div>One half (and a bit extra width) ends up at either 84 of the "industrial" 14mm tiles or 77 of the "normal" 8mm tiles. Will the 8mm ones be ok or do you think I need Industrial strength given the weight of the car standing in one place for extended time periods?</div></blockquote>
<div><br></div><div>Well, the 8mm ones do show a picture of a car sitting on them, and they're rated for garage/light industrial so I reckon they'll be absolutely fine. I'm basing this on the fact that I'm very happy with the quality of my 14mm ones, so I reckon they'd only sell the 8mm ones if they were also convinced about their quality too.</div>
